Kaze Master is able to control and monitor up to 4 fans, and 4 temperature monitor independently. These figures are displayed on VF-Display. To safely monitor and run your system, Kaze Master comes with the alarm feature to inform the user in case of fan malfunction. Also if the temperature goes above 75°C (165F), or in case of the temperature sensor failure, VF-Display will blink the number "0" or "0.0" and trigger the alarm sound. The alarm sound disturbs you? You can even shut down the alarm sound by a simple jumper setting! Both Celsius and Fahrenheit unit can be displayed by a simple jumper setting! By turning the knob to counter-clockwise all the way, the fan can be stopped. You can control fans between 3.7V – 12V to meet your needs for system requirement. By setting the voltage to the lowest level can silence your PC or turn it up to the highest to get the maximum cooling performance.
